This is Steve Ballmer, 2012, pitching Windows Phone 8 with serenity, emotion, and conviction. It's pretty good!
Below is Steve Ballmer, 1986, hawking Windows 1.0 to an unsuspecting public with enough verve and spittle to wake (and terrify) the dead. It's pretty awful!
So well done, Steve Ballmer. A few more years and you'll be right up there with Mayhem.
